UNITE STATES JAMES MGINTYRE, OF EDMONTON, CANADA.

FOLDING SCAFFOLD-BRAOKET.

Specification of Letters Patent.

Patented Jan. 16, 1906.

Application filed May 29, 1905. Serial No. 262,829.

To all whom it may cmwern.

Be it known that 1, JAMES MoINTYnE, a subject of the King of GreatBritain, residing at Edmonton, District of Alberta, North- VVestTerritories, Canada, have invented a certain new and useful Improvementin Folding Scaffold-Brackets, of which the following is a specification,reference being had to the accompanying drawings, which form a part ofthis specification.

My invention has for its object to provide a novel foldingscaffold-bracket of simple and economical construction and of superiorutility.

The desirability of a scaffold-bracket which will be permanent, durable,easily folded up, and readily set up for use is apparent.

I carry out my invention as hereinafter described and claimed, andillustrated in the accompanying drawings, in which Figure 1 is a view ofthe device in side elevation in position for use. Fig. 2 is a view inside elevation, showing the bracket in folded position. Fig. 3 is adetail View in perspective, showing a portion of the device; and Fig. 4is an end view of the brackethead.

A bracket-head a is employed formed with bands I) b to receive the innerend of a supporting-arm 0. One end of the bracket-head is constructed inthe form of a hook (I, to engage the lumber already in place upon a sideof the building, as shown in Fig. 1. have shown the bracket-headprovided with a hook, I would have it understood that I do not limitmyself solely thereto, as the brackethead may be engaged in place in anysuitable manner within the scope of my invention. The inner end of thesupporting-arm is preferably bolted to the bracket-head between thebands I) b, as shown at e. The brackethead is also provided with ears f,to which may be fulcrumed, as indicated at h, a swinging brace g. Towardthe outer end of the supportingarm c I locate thereupon a coupling j,said coupling preferably constructed with a band It, through which ispassed the outer end of the supporting-arm. Said coupling is alsoprovided with ears on its under side, to which may be fulcrumed asupporting-brace m, as indicated at a. The lower end of the swingingbrace g is provided with a band or stirrup i, through which the innerend of the supporting-brace is passed, the supporting-brace beingconstructed with a shoulder 1), against which the stirrup may engage tohold the WVhile 1' two adjacent parts firmly in position. I prefer thatthe hook (1 should be provided with a downwardly-projecting flange q toform a substantial bearing against the lumber already upon the buildingand also that said bracket-head should be extended transversely of thesupporting-arm, as indicated at 1" 1 Fig. 4, also to form a substantialbearing.

It will be evident that the supportingbrace m and the swinging brace 9may be folded up under the supporting-arm when the bracket is not inuse, as indicated in Fig. 2. This is readily accomplished by lifting thesupporting-brace upward within the stirrup or band i, so as to permitthe stirrup or band to slide over the shoulder 2), said stirrup or bandfolding up under the supportingarm adjacent to the outer coupling j. Thelower end of the supporting-brace m is constructed to engage against theouter face of the building upon which it may be placed, as indicated inFig. 1. It is will be evident that when the stirrup i is engaged againstthe shoulder p and the brackethead is engaged in place, as described,the supporting-arm a will be effectually braced and held in placeagainst a building. the weight upon the scaffold-bracket the more firmlywill it be held in place. It is also obvious that the device may readilybe taken down and set up and when in folded position it may be readilytransported and stored in compact form.

Vhat I claim as my invention is 1. A folding scaffold-bracket comprisinga horizontal supporting-arm, a folding supportingbrace jointedlyconnected with said arm toward the outer end thereof, a swinging bracejointedly connected with the supportingarm toward the inner end thereof,said supporting-brace formed with a shoulder inter mediate ends thereof,and said swinging brace with a stirrup or loop to encircle thesupporting-brace and to engage the shoulder to hold the two braces inworking position, the supporting-arm provided with means for engagingthe same in place upon a building.

2. A folding scaffold-bracket comprising a supporting-arm, a foldingsupporting-brace, a couplingtoward the outer end of the supporting-armto which the supporting-brace is jointedly connected, a bracket-headupon the opposite end of the supporting-arm, and a swinging bracejointedly connected with the bracket-head, and provided with a stir-Obviously the greaterrup at its opposite end encircling the sup- 7porting-brace, said supporting-brace provided with a shoulder to engagethe stirrup, said bracket-head constructed to be engaged upon abuilding.

3. A folding scaifold-bracket comprising a supporting-arm, a foldingsupporting-brace, a coupling toward the outer end of the supporting-armto which the supporting-brace is jointedly connected, a bracket-headupon the opposite end of the supportingarm provided with bands spacedone from the other to receive the inner end of the supporting-arm, aswinging brace j ointedly connected with the bracket-head and providedwith a stirrup at its outer extremity encircling the supporting-brace,means passed JAMES MGINTYRE.
